Answer:

\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1

Step-by-step explanation:

In this problem we have a horizontal ellipse, because the major axis is the x-axis

The equation of a horizontal ellipse is equal to

\frac{(x-h)^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}} =1

where

(h,k) is the center of the ellipse

a and b  are the respective vertices distances from center

we have

vertices at (7, 0) and (-7, 0)

co-vertices at (0, 1) and (0, -1)

so

The center is the origin (0.0) (The center is the midpoint of the vertices)

a=7

b=1

substitute

\frac{(x-0)^{2}}{7^{2}}+\frac{(y-0)^{2}}{1^{2}}=1

\frac{(x)^{2}}{49}+\frac{(y)^{2}}{1}=1

A movie theater sold 500 tickets on
Natasha2012 [34]

Answer:

45%

Step-by-step explanation:

225 of 500 can be written as:

225/500

To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100

225/500 × 100/100

= (225 × 100/500) ×

1/100

=

45/100

Therefore, the answer is 45%

Hope this helps :)

The number of adult tickets is the same as the number of child (age5-12)tickets.A total of 38 tickets was purchased. What is the
Nutka1998 [239]

Answer:

$760

Step-by-step explanation:

The number of adult ticket is the same as the number of (age 5-12) tickets.

Let the number of adult ticket be x

Number of (age 5-12) tickets be x

Total ticket sold = 38

x + x = 38

 2x = 38

  x = 19

Cost of each adult ticket = $23

Total cost for 19 such tickets = 23×19

                                               = $437

Cost of each (age 5-12) ticket = $17

Total cost for 19 such tickets = 19×17

                                               = $323

Total cost of 38 tickets = 437 + 323

                                       = $760

Hence, the total cost of tickets is $760

Which distribution has the greatest spread?
Juli2301 [7.4K]

Here, the <em>standard deviation </em>is the best measure of the spread of a data set. The higher the standard deviation, the more spread out the distribution is. In this case, the distribution with the highest standard deviation (and therefore the greatest spread) is Distribution 3. Its low mean might be deceptive, but the value of a data set's mean has no effect on its spread.
